LEMUEL I. COULTER, OF TACOMA, WASHINGTON.

BURNER.

To all whom it may concern:

Be it known that I, LEMUEL P. CoULTER, a citizen of the United States, residing at Tacoma, in the county of Pierce and State of WVashington, have invented new and useful Improvements in Burners, of which the following is a specification.

This invention relates to a hydro-carbon burner of the type in which the retort tube is suspended over the flame and heated thereby.

An object of the invention is to provide, on the retort tube directly .bove the flame, a corrugated radiator which due to its mass acts as an accumulator for heat which it imparts to the retort and likewise furnishes a support for any articles that it may be desired to place over the flame from the burner.

A further object is to construct theparts of the burner of such design that they are readily fabricated and assembled in such manner that a complete burner may be produced at abnormally low cost.

WVith the above and other objects in view, I will now proceed to describe a specific embodiment of the invention, and with reference to the accompanying drawings, forming a part of this specification and in which Figure 1 is a top plan view of the burner.

Fig. 2 is a side elevation.

Fig. 3 is a section on line 3-8 of Fig. 1.

Fig. 1 is a section on line 4-4 of Fig. 1 and Fig. 5 is a top plan view of a modified form of burner.

In detail The burner comprises a base 1 having a depending flange 2 which houses an integrally cast tube 3 open at both ends, said ends being threaded to receive plugs 5 which may be removed to clean deposits out of said tube 8; this method of forming the base and tube with the ends of the latter open also makes an easy job of casting since the hole through tube 8 is easily cored for casting and may be readily cleaned out in finishing the casting. Directly over the. center of the tube 3 is an opening 6, the edges of which carry an upwardly extending flange 7. nozzle outlet 8 is screwed into the tube 3 centrally of the opening 6 and interposed in the tube 3 directly in port of the nozzle outlet 8 is a screen 9. An inlet 10 provided Specification of Letters Patent.

with a screen 11 leads out from tube 311;) a boss 12 on the face of the base 1.

Over the flanged opening 6 is placed a carbureter 13 which is formed asto leave an air intake space 14 betweenthe inner walls of the carbureter, the flanged walls 7 and the top of the base 1, the carbureter 13 has a centrally disposed opening surrounded by an outstanding flange 15 directly over which is located a radiator mass 16 having an under corrugated surface 17, said radiator being carried by a retort tube 18, one end of which is screwed into the opening 10 and the other end 19 of which carries a union 20, for connection to any suitable fuel supply valve. The retort tube 18 is filled with brass wires which transmit the head intimately to the fuel therebycausing the fuel to quickly vaporize and pass to the carbureters. To provide for a'circulation of air through the bottom of the carbureter 13, the latter has its lower edge formed with spaced depending feet 13'.

If desired the retort tube may be formed as shown in Fig. 5, wherein the retort tube 19 carrying the corrugated radiator 20 is curved around to form a support for any article which it may be desired to place over the flame from the burner.

invention it is nevertheless to be understood that, in practice, I may resort to any and all modifications falling within the scope of the appended claims defining the invention.

Having thus described my invention what I claim as new is 1. In a hydro-carbon burner, a flanged base cast to provide a tube which extends centrally therethrough, means closing the ends of the base, a burner nozzle arranged centrally on the top of the tube and communicating with the bore thereof, the top of the base having a flanged opening surrounding the tube, an air mixer comprising a member arranged over the flange of the opening, spaced therefrom and from the top of the base, said member having a central opening surrounded by an outturned flange,

a retorttube disposed above the base havingv an offset branch communicating With the tube in the base, and av flame spreader on the retort tube disposed directly above the air mixing member.

2. In a hydro-carbonburner, a base comprising a flat top having downwardly flanged sides and ends and cast With a central tube therethrough, removable means closing the ends of the tube, a screen in the tube, a burner nozzle centrally'connected to the top and communicating with the tube, the top ofthe base having a flanged opening surrounding the burner nozzle "and in which the latter is'received, an air mixer comprising a member surrounding the flange, spaced from the Walls thereof and having its lower edges provided With feet an angle branch connected With said pass sage, and a flame-spreader having a lower corrugated facedisposedover the mixer.

In testimony whereof I afiix my signature.
